I have an issue with my Rpi4 and my screen. I just installed a Raspian version on my SD card and I can see the starting of my Rpi4 (with all the lines) but I lost the signal of my screen just after. I can access to my Rpi with SSH but I would like to keep the screen in case of problem.
I tried to plug in both of the small HDMI port without any change. My screen is a Dell brand (model S2421HS) and works well.
Could you please help me to resolve this problem ?
Many thanks. Smilorel
